Description

  The present invention is applicable to machine tools, robots, PLCs, transfer machines, measuring instruments, test devices, press machines, press-fitting machines, printing machines, die casting machines, injection molding machines, food machines, packaging machines, welding machines, washing machines, and coating machines. , Control systems and control methods for industrial machines such as assembling machines, mounting machines, woodworking machines, sealing machines or cutting machines, in particular, changing between CNCs and PCs on the machine tool side and between devices such as multiple CNCs The present invention relates to a control system and a method for aligning acquired data.

As is well known, in the field of machine work, CNC (Computerized Numerical Control) technology is applied, and the same machining procedure is repeated by performing numerical control of a moving amount and a moving speed of a tool by a computer. Highly automated shape processing. In addition, data from a PC (Personal Computer) created by CAD or CAM is taken in and reflected on a machine tool such as an NC lathe or a machining center, and integrated automation is performed from design to manufacturing (for example, see Patent Document 1). .

JP-A-07-261818

  On the other hand, for example, when the machining time of the CNC is predicted on the PC or the machining simulation is performed, various data of the CNC, such as options, parameters, NC programs, macro programs, macro variables, and work origins are previously stored on the PC side. It is necessary to transfer offsets, tool offsets, tool shape data, tool management data, and the like to match and match the content information.

Further, when there are a plurality of machine tools, there is a case where it is desired to make the contents of various CNC data coincide between the machine tools.

In general, when matching the data content between the PC and CNC devices or matching the data between a plurality of machine tool devices, all types of data (options, parameters, NC Programs, macro programs, macro variables, work offsets, tool offsets, tool shape data, tool management data, etc.) I have.

  However, for example, each type of data area is further divided into a plurality of areas, and in this case, between a certain timing and another timing, data of which type area, further data of which divided area, and much more data Can't tell where has changed (can't know quickly).

For this reason, when it is desired to match the contents of various data between the CNC and the PC or between the CNC and the CNC, if all types of data are transferred, it takes time in a minute unit due to the large amount of data, and the processing takes place. It takes a lot of time and effort. Further, since the operation flow, that is, the work flow is interrupted, the operability and, consequently, the productivity are reduced.

Here, the processing time can be shortened by selecting and transferring only the data of the changed type by the operator, but the operator can memorize which type of data has been changed by himself or visually. Since it is necessary to confirm, an increase in work load becomes a problem.

Furthermore, even if only the data of the changed type is selected, only the changed portion in the data cannot be transferred, so that it takes several tens of seconds depending on the type, and the processing time increases. Will be.

  Since the invention described in Patent Document 1 transfers the drawing data designed / changed on the PC side to the NC machine tool, the data on the NC machine tool side cannot be reflected on the PC side. However, it is not possible to match data of a plurality of machine tools. For this reason, the inconvenience described above cannot be eliminated.

  In view of the above circumstances, the present invention can efficiently and effectively match and match the content information of various data between devices of an industrial machine, and can reduce processing time, operability, It is an object of the present invention to provide a control system for an industrial machine, which makes it possible to improve productivity and reduce a burden at the time of work.

  The inventor of the present invention has found, for example, a method of automatically determining the type of changed data and the changed portion when it is desired to match and match the content information of various data between CNC and PC or between CNC and CNC. The present invention has been completed. More specifically, the present invention provides the following.

And a work execution unit for performing a desired work using various data, wherein the update data processing unit is configured to store the area with the identifier in the change data identification list. And confirming whether or not the data has been changed, and sending only the data in the changed area to the other device to match the data of the own device and the data of the other device.

(2) In the industrial machine control system according to (1), in the case of a one-to-one connection environment between one of the own device and one of the other devices, data of the data is used as the identifier. A flag for identifying one of the two states of the initial state and the changed state may be used.

(3) The present invention relates to the control system for an industrial machine according to (1), wherein the connection environment is one-to-one or one-to-many connection between one said device and one or more other devices. The identifier may be incremented or decremented each time data is changed, and a counter for identifying an initial state of data and a change state of the number of times of data change may be used.

(4) In the industrial machine control system according to (2), the flag is reset to the initial state when data of the changed area is sent to the other device. May be.

(5) In the control system for an industrial machine according to any one of (1) to (4), the change data identification list may include the division information of the type data storage unit that is the highest classification of the type data. The identifier storage section may be provided for each of the indicated areas, and the identifier storage section may be provided for each of the areas indicating the division information of the subdivision data type storage section as the lower classification.

Hereinafter, a control system for an industrial machine according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 5.

Here, in the present embodiment, an example will be described in which change data is transferred and matched and matched between one-to-one devices between a CNC on one machine tool and one PC. . In the present embodiment, an explanation will be given assuming that the industrial machine according to the present invention is a machine tool (the own device is a machine tool, and the other device is a PC). However, the present invention is, of course, applicable to other industrial machines. Is also applicable.

The control system A for an industrial machine according to the present embodiment is a “flag-based” control system and method. As shown in FIGS. 1 and 2, for example, options, parameters, NC programs, macro programs , Macro variable, work origin offset, tool offset, tool shape data, tool management data, etc., the areas of the highest classification 10 (areas (division information) 10a, 10b, 10c,... ) And an area of the data type of the lower class 11 by further subdividing the area 10a, 10b, 10c... ), 11a, 11b, 11c, 11d, 11e,...) For each of the data areas of the class 11, a "changed data identification list" 13 including an area (identifier storage unit 12) for storing a flag (identifier) for identifying a change when it is changed is used. .

In other words, in the control system A of the industrial machine of the present embodiment, the types and data are hierarchized as an area of the highest classification 10 and an area of the lower classification 11, and all types and data of each hierarchy are The “change data identification list” 13 is configured by providing an identifier indicating whether or not there is a change. Note that the area of the lower classification 11 may be further subdivided, and the “change data identification list” 13 may be configured to include a plurality of lower classifications 11 (multi-layered).

Here, the “flag” according to the present invention indicates one of two states of an initial state and a changed state of data, and is an identifier for judging these states. In the present embodiment, the description will be made assuming that the identifier “flag” represents “0” for the initial state of the data (the state in which the data is not changed) and “1” for the changed state of the data (the changed state). .
The “flag” of the identifier may be “O and X” or “A and B” as long as the two states can be identified so as not to be particularly limited.

  Here, as shown in FIG. 2, the control system A for the industrial machine according to the present embodiment stores a "change data identification list" 13 in the CNC 1 of the machine tool as its own device. A data storage unit 4 for storing various data (a data storage unit on the own device); an update data processing unit 5 for performing a flag initialization process, a flag setting process, a flag confirmation process, a data transfer process, and the like; It has.

Further, various data storage units (other device side data storage units) 6 for storing various data in the PC 2 for performing desired operations such as processing time prediction and processing simulation by the machine tool in association with the machine tool, A work execution unit 7 for performing a desired work using application programs such as data and machining time prediction software and machining simulation software;

  When controlling the CNC 1 and the PC 2 of the machine tool using the industrial machine control system A of the present embodiment having the above configuration, first, as shown in FIG. 3A and FIG. / When the power of the machine tool is turned on, the flag of each data type in the 10 highest-order classification area of the “change data identification list” 13 (flag for each data type, identifier storage unit 12 of type data storage unit 10) Further, all the flags of each layer of the flags of the areas of each data type of the lower class 11 (the flags for each changed part, the identifier storage unit 12 of the small division data type storage unit 11) with respect to the area of the top classification 10 Is cleared to “initial value = 0” (Step 1).

  As shown in FIG. 3B and FIG. 4B, when the data of the CNC 1 is changed, the flag corresponding to the changed data (the identifier stored in the small section data type storage unit 11 Unit 12), and set the flag of the "flag for each data type (identifier storage unit 12 of type data storage unit 10)" to which the changed data corresponds to "1" (Step 2 and Step 3).

  Then, when matching / coinciding the changed data on the CNC side with the data on the PC side, as shown in FIGS. 2 and 5, the changed data identification list storage unit 3 of the CNC 1 reads “changed data identification”. .., And “Flag for each data type (flag of identifier storage unit 12 for each type data storage unit 10)” is displayed for each data type of areas 10a, 10b, 10c,. Check whether it is "1".

  If the flag for each data type is “0” (not “1”), it is checked whether the flag for each data type is “1” for the next data type. (Step4, Step5).

  If the flag for each data type is "1", the flag for each change location in the areas 11a, 11b, 11c, 11d, 11e,. It is confirmed whether or not the flag of the identifier storage unit 12 is “1” (Step 6 and Step 7).

  If the flag for each change point is “0” (not “1”), it is checked whether the flag of the next change point (identifier storage unit) in the same area is “1”. (Step 8).

  If the flag for each changed part is “1”, the change data of the changed part (the part corresponding to the small section data type storage unit 11) in which the flag for each changed part is “1” is stored. The data is transferred to the various data storage units 6 of the PC 2 (Step 9). After transferring the data of the location (area) where the flag is "1", the flag of that location is reset to "0" in the initial state (Step 10). Thereafter, the checking of the flag for each of the other changed portions is restarted (Step 8).

  Then, the flag of the type to which the data was transferred is reset to "0" (Step 11), and the same flag confirmation operation and data transfer as described above are performed for the next data type (Step 12).

  If this operation is performed for all data types, both the CNC 1 and the PC 2 have the same changed data, and it is possible to match the data between the devices.

For example, when one PC 2 is connected to the CNC 1 as in the present embodiment, the type of changed data and the changed location are determined by the above-described “flag method”, and the data ( Area) to the PC2. As a result, it becomes possible to perform machining time prediction, machining simulation, and the like on the PC 2 by using the application software and reflecting the changed data.

  Therefore, in the control system A of the industrial machine of the present embodiment, it is possible to easily determine the changed data type and the changed portion only by checking the flag.

Therefore, according to the industrial machine control system A of the present embodiment, for example, when it is desired to match / match the content information of various data between the CNC and the PC or between the CNC and the CNC, the changed data type is determined. The determination can be made automatically, and the processing time can be reduced by transferring only the data area of that type. In addition, the operability and, consequently, the productivity can be improved.

In addition, since the changed data type can be presented / extracted, the operator does not need to rely on storage or visual confirmation when selecting the type of data to be transferred, and can reduce the work load.

Further, since the changed portion in the data can be automatically determined, the processing time of the data transfer can be reduced.

As described above, the first embodiment of the control system for an industrial machine according to the present invention has been described. However, the present invention is not limited to the above-described first embodiment, and can be appropriately changed without departing from the gist thereof. is there.

Next, a control system for an industrial machine according to a second embodiment of the present invention will be described with reference to FIGS.

Here, in the present embodiment, an example will be described in which change data is transferred between one CNC and two PCs and is matched and matched between one-to-two (plural) devices. In the present embodiment, the description will be given on the assumption that the industrial machine according to the present invention is a machine tool (the own device is a machine tool, and a plurality of other devices are PCs). It is also applicable to machines. Further, in the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

The control system B of the industrial machine according to the present embodiment is a control system and method of a “counter method”. As shown in FIG. 6 and FIG. The areas 10a, 10b, 10c,... Of the data storage section 10 and the areas of the data type of the lower classification 11, which are obtained by further subdividing the areas of various types of data of the top classification 10 (small division data type storage section). ..), The data area of the type of each highest class 10 and the data area of each lower class 11 when there is a change. A "change data identification list" 14 having a counter (identifier) for storing the identifier (identifier storage unit 12) is used.

In other words, in the control system B of the industrial machine of the present embodiment, as in the first embodiment, the types and data are hierarchized as the area of the highest classification 10 and the area of the lower classification 11, and all the types in each hierarchy are classified. , An identifier indicating the presence or absence of a change is provided for each of the data, and the “changed data identification list” 14 is configured. As in the first embodiment, the area of the lower classification 11 may be further subdivided, and the “change data identification list” 14 may be configured to include a plurality of lower classification areas (in a multi-layered manner).

  Here, as shown in FIG. 7, the industrial machine control system B of the present embodiment stores the "change data identification list" 14 in the CNC 1 of the machine tool, which is its own device (the current counter is stored). To perform the change data identification list storage unit 15, various data storage units (own device data storage unit) 4 for storing various data, counter initial processing, counter setting processing, counter confirmation processing, data transfer processing, and the like. And an update data processing unit 16.

Furthermore, in the industrial machine control system B of the present embodiment, various data storage units (other device-side data storage units) 6 for storing various data are stored in a plurality of PCs 2 for performing desired operations. A work execution unit 7 for performing a desired work using application programs such as data and machining time prediction software and machining simulation software, and a “change data identification list” 14 before update are stored (counters before change are stored in a counter). And a (pre-update) counter storage unit 17.

  When controlling the CNC 1 and the plurality of PCs 2 of the machine tool using the industrial machine control system B of the present embodiment having the above configuration, first, as shown in FIG. When the power is turned on, the counter of each data type in the area of the highest classification 10 of the “change data identification list” 14 (a counter for each data type, the identifier storage unit 12 of the type data storage unit 10), and Clear all the counters of each layer of the counter of the area of each data type of the lower classification 11 (the counter for each change location, the identifier storage unit 12 of the subdivision data type storage unit 11) to “initial value = 0” (Step 1). ).

  As shown in FIG. 8B and FIG. 9B, when the data of the CNC 1 is changed, the changed data corresponds to the “counter for each changed part (the identifier storage in the small section data type storage 11). Unit 12) ”, and the counter of the“ counter for each data type (identifier storage unit 12 of type data storage unit 10) ”corresponding to the changed data is incremented by 1 to indicate / record the number of changes. (Step2, Step3). The counter may be set in advance and, when data is changed, -1 (decrement: decrement) to indicate the number of changes.

  Then, when matching / coinciding the changed data on the CNC1 side with the data on the PC2 side, as shown in FIGS. 7 and 10, the current “changed” is stored in the changed data identification list storage unit 15 of the CNC1. In addition to reading out the “data identification list” 14, the pre-update “changed data identification list” 14 is read from the pre-update counter storage unit 17 of each PC 2, and the current “changed data identification list” 14 and the pre-updated The difference between the values of the corresponding type counters in the “change data identification list” 14 is calculated (the counters are compared: Step 5 and Step 6). That is, it is confirmed by comparing whether or not the values of the respective counters are different.

  In the present embodiment, when the difference between the values of the type counters corresponding to the current “changed data identification list” 14 and the “changed data identification list” 14 before the update is found, the difference is “0”. In the case, there is no change in the data of the area, and when the difference is “1”, the data of the area is changed once, and when the difference is “2”, the data of the area is changed twice. You can see that.

  If the difference between the counters for each data type is “0”, it is checked whether or not the counter for each data type has a difference with respect to the next data type (Step 7).

On the other hand, when the difference is “1 or more”, the counter (the identifier for each subsection data type storage unit 11) for each change location of the areas 11a, 11b, 11c, 11d, 11e,. It is checked whether the difference of the counter of the storage unit 12 is “1 or more” (Step 8 and Step 9).

  If the difference of the counter for each change point is “0”, it is checked whether the difference of the counter of the next change point (identifier storage unit 12) in the same area is “1 or more” (Step 10). .

  When the difference of the counter for each changed part is “1 or more”, the changed data of the changed part (the part corresponding to the small section data type storage unit 11) for each changed part is stored in various data on the PC 2 side. It is transferred to the unit 6 (Step 11).

The counter of the sequentially changed portion and the counter of the data type are checked, and the above operation is repeated.

If it is confirmed that the type counter is different and the change has been made, the data of the changed portion of the data type is transferred to update the “changed data identification list” 14 of the plurality of PCs 2 before the change. / Save by overwriting. In addition, even if the counter has not been changed, in order to retain the history of the counter comparison, data is transferred from the CNC 1 when all the counter comparison operations are completed, and the “change data identification” before the change of a plurality of PCs 2 is performed. It is preferable to update / overwrite and save the “application list” 14.

  If this operation is performed for all data types, both the CNC 1 and the plurality of PCs 2 have the same changed data.

  Therefore, in the industrial machine control system B of the present embodiment, the current set of counters is obtained and compared with the stored counters before the change, so that the changed data type and the changed location can be easily determined. It becomes possible to do.

Therefore, according to the industrial machine control system B of this embodiment, for example, when it is desired to match / coincide the content information of various data between a CNC and a plurality of PCs or between a CNC and a plurality of CNCs or PCs, The type of data that has occurred can be automatically determined, and processing time can be reduced by transferring only the data area of that type. In addition, the operability and, consequently, the productivity can be improved.

In addition, since the changed data type can be presented / extracted, the operator does not need to rely on storage or visual confirmation when selecting the type of data to be transferred, and can reduce the work load.

Further, since the changed portion in the data can be automatically determined, the processing time of the data transfer can be reduced.

As described above, the second embodiment of the control system for an industrial machine according to the present invention has been described. However, the present invention is not limited to the above-described second embodiment, and includes the modifications of the first embodiment. It can be changed as appropriate without departing from the spirit.

  For example, the counter-based control system and control method of the present embodiment can be applied to a case where changed data is transferred between one-to-one devices to match and match the same as in the first embodiment. Further, the present invention may be applied to a case where data between a CNC and a plurality of CNCs and PCs is matched and matched.
